Passage of the pollen tube through the micropyle of an ovule in a seed plant.

Porogamy

the usual route by which a pollen tube enters an ovule—via the micropyle—in the fertilization of angiospermous and gymnospermous plants. When the pollen tube penetrates the ovule by a different route, the process is called aporogamy (for example, penetration of the chalaza is known as chalazogamy).
